Description

Technical Field

[0001] The utility model relates to the field of electric heating air guns, in particular to an air gun heating frame and a wave-type heating air gun. Background Art

[0002] A hot air gun is a common electric heating tool. It uses the principle that the heating core will heat up after being energized to heat the blown air and provide hot air. The wiring terminals in the existing hot air gun usually include a bridge piece and a wire-wrapped terminal. The current is conducted through the cable, the wire-wrapped terminal, the bridge piece and the heating core. There are multiple overlaps, and the contact resistance is large, which causes oxidation and burning at the overlap or reduces the heating efficiency of the heating core due to a large voltage drop. The bridge piece is fixed to the hot air gun by bolts and nuts, and the nuts are easy to loosen, resulting in poor contact, and the power cannot be continuously supplied, so that the heating core cannot heat continuously. Among them, a heating duct and a hot air gun with the application number "CN202220541442.7" are provided. The present application connects the heating core to the cable through an integrated wiring terminal, reduces the number of overlaps, reduces the contact resistance, and improves the heating efficiency of the heating core. A protrusion is provided at one end of the bridge piece. When the bridge piece is installed on the heating bracket by bolts and nuts, the protrusion presses against the nut to prevent the nut from rotating when the bolt is turned, which is convenient for installation. However, there is still room for improvement in the internal heating structure of the hot air gun: the heating device of the hot air gun is a traditional slingshot wire structure, which will cause the heating wire to come into hard contact with the white ceramic, making the heating wire easy to break, and the hot air gun is fixed with screws, making it difficult to make the structure waterproof and dustproof, thereby reducing its service life.
